here, I also did the work for you, is the page that describe wordpress:

I also created a prompt for chatgpt:

"i'm not clear, what the difference of shopify compared to wordpress is. can you tell me what shopify is used for, what is wordpress is used for? My idea is to create an AI-powered platform for e-commerce and content management, also focused on personalizing websites."

And I also asked my personal gpt with "hey gpt, there is a guy who wants to combine wordpress and shopify and create an AI-powered platform for e-com and cms-functionality, but is asking for hands-on experience with shopify. will he succeed?"

gpt told me too much, but the essence is you'll most probably will fail, because you want to build, but don't even want to invest the time to look for the differences or the "what is it all about". gpt especially put emphasis on its question "does he plan to use vibe coding or is this guy is just lazy?" I dunno, was my answer. So gpt told me to give you the links, so it can be checked if you're just lazy, or really not capable to do the basic research. But, I don't care - its up to you to find your way. Have fun and success, my friend!

For WordPress, check out WooCommercd, an e-commerce plug-in by the same company that makes WordPress.

You're entering a very crowded space that already has a lot of established players. Wix and Squarespace also do similar things, including with AI.
